Everyone loves the magical world of Harry Potter, but did you know you can learn some cool things about history, science and medicine from reading the books, too? Were there ever really dragons, unicorns and basilisks? Was there a Sorcerer’s Stone? The magic in J. K. Rowling’s series of Harry Potter novels is partially based on Renaissance traditions that played an important role in the development of Western science, including alchemy, astrology, and natural philosophy. Harry Potter's World: Renaissance, Science, Magic, and Medicine explores the intersection of these worlds, featuring highlights from the collections of the History of Medicine Division at the National Library of Medicine.
